SECIFTCATlQN forming partof LettersPatent No. 691,164, dated January 14, 1902. Application filed March '7, 1901. Serial No. 50,237. (No model.)

To all 1071/0112/ may concern,.- p

Beit known that I, GEORGE` W. MCGILL, a citizen of the United States, residing at Riverdale-on-the-Hudson, New. York city, in the county of New York and State of New York, have invented new and useful Improvements in Spring-Buttons or Fastening Devices, of which the following is a specification.

My invention relates to spring-buttons or fastening devices for leather purses, umbrellas, and other articles of that class in which stud and socket members are employed adapt-` to be insertedone within the other and to interlock with each other.

The object of the invention is to provide cooperating engaging means on the two members independent of the locking means for preventing lateral displacement of one of said members with respect to the other.

A further object of the invention is to provide means on the stud member whereby increased strength and resilience in the spring portion may be obtained and a more reliable snap or locking action between the stud and socket members effected.

A further object of the invention is to provide on the socket member increased capsupportiug strength and means for spreading and retaining in position the radiating spring-sections of the stud member,and thereby increasing the locking action thereof.

A further object of the invention is to provide improved means for attaching the two members of the button or fastening device to the fabric or article of apparel on which the same are to be used.

A further object of the invention is to reduce the number of parts of which the stud and socket members are made and to provide means for preventing lateral or horizontal turning movement of said members when the same are in locking relation to each other.

Other objects and advantages of the invention will Vhereinafter appear, and the novel features thereof will be set forth in the claims. 0

Like reference-numerals indicatelike parts in the different views.

The stud member l of my improved button or fastening device is made from a disk ofV sheet metal struck up to form the stud 2 and the baseiiange The stud 2 is struck or spun inwardly at its center to form a central re'entrant conoidal-shaped cavity4 on the outside or upper surface thereof and an anvil 5 of conoidal shape on the inside or lower surtween its annular wall and the dependent wall of such conoidal-shaped rentrant cavity, said walls being in curved and integral connection at their top,providing an arched cover or roof to the annnlus between and dividing them. lies in substantially the same plane with the base-flange 3, and the stud 2 is formed with a plurality of vertically-disposed radially-arranged slots 6, providing for the compression of the outer and inner or concentric walls of the stud 2. substantially cylindricalportion or neck 7at a point adjacent to the base-liange 3, and from said cylindrical portion or neck it bulges outwardly, forming a bulging upper portion or head to provide an engaging portion on its outer surface. By providing the rentrant cavity 4 in the stud 2 the said stud is annular, and when the same is pressed inwardly it acts against the resiliency of the two part-s The lowermost point of the anvil 5 The said stud 2 is formed with a i face thereof, with a covered annulus #i8 be- IOO or concentricwa-llsot' the curved metal of which itis formed-that is to'say, when the stud 2 is laterally compressed the resistance to be overcome is that'offered bythe mate- 5 rial of said stud forming its concentric cony nected walls or from the cylindrical portion or neck 7 of said stud to its upper fold forming its annular top or crown and that offered by the resiliency of the material from the up- Io per fold or head of said stud down to the anvil 5. When, therefore, the lateral compression of said stud is relieved, said stud returns to its normal outward position by the springing outwardly of the arms formed by the slots I5 6 and the springing upwardly of the inner part of the stud above the anvil 5. To the under side of the flange 3 is secured a basevplate 8, the same being heldin place by crimping or upsetting the edge of the base-fiange zo v3 around or over the edge of the base-plate 8, as shown at 9. At the center of the base- 'plate 8 is vau upwardly-projecting annular eX- tension or collar 10, which embraces the anvil 5 of thestud 2 and serves to hold said stud in proper position with respect to the .baseplate S-that is to say, through the engagement of the anvil 5 with the extension 10 lateral movement of the anvil 5 and of the stud 2 as a whole is prevented. As shown, the upper 3o end of the tubular extension 10 is flared outwardly to conform to the shape of the anvil 5. The ange 3 and the plate 8 unit'edly constitute the base of the'stud member. When it is desired to attach the stud member 1 to the cloth or fabric to which it is to be applied,

an opening is cut in the cloth of a size corresponding to the base diameter of the exten- `sion 10, and the base of the stud mem-ber is placed against the cloth, with the opening in 4o the latter lying opposite said extension 10.

The -eyelet 11 is now brought into use. The

same is preferably of the same diameter asthebase of the stud member 2 and is formed with a central tubular extension 12. This extension 12 is inserted through the opening in the cloth or fabric 13 from the side thereof opposite that on which the stud member 1 is placed and forced up into the extension 10 of the base-plate 8. In so doing the upper edges 5o of the extension 12 come in contact with the an'vil'5 and are spread or ared outwardly, so `that they lie in close contact with the innersurface of the flared 'extension 10 on the base-plate 8. Said eyelet 11 is in this manner secured to the vbase-plate 8,'and the stud member yas a' Whole is rmly attached to the cloth or fabric 13. Danger of accidental displacement of the parts is thereby effectually prevented. Of course when the eyelet 11 is oe being forced into its place the anvil-head of center to form a central cavity 18, having a dome 49, side walls 19,flaring outward at their top, as shown at 20, and that portion of the dome connecting therewith bent inwardly and downwardly to form the inclined anvil-groove 21 and then upwardly and againdownward and inwardly to form a central depression or cavity 22, the under side of which constitutes an engaging portion 23 and annular supporting ribs or {ianges 24 25, separated by an annular ygroove or depression 26. The ribs or projections 2425 of the dome engage the inner surface of the crown 1 6 and serve asia support therefor to preventthe bendingor collapsing of said crown. The part 23, formed by the inwardly-extending cavity or recess 22, constitutes an engaging portion which fits within the cavity 4 in the stud member 1 when the two members are in interlocking re` lation' with each other and prevents, independent of the main locking means, the lateral dis-placement of one member with respect to the other, requiring a direct verticalmove m ent to secure their separation. The socket member 14 is attached to the cloth or fabric by means of an eyelet 27, consisting of a base 28, a tubular extension 29 at the f center thereof, and an inwardly-projecting annular bead 30 between the flange 28 and the extension 29. The bead 30 forms a contracted throat for the socket member and provides a shoulder against which the stud 2 bears when the two members of the device are in locking relation one to the other. An opening is cut or otherwise formed in the cloth opposite the cavity 18 in the socket member 14, and the extension 29 of the eyelet 27 is introduced through this opening and into the cav-l ity 18. When the upper edges of the extension 29 come in contact with the lower surface of the upper wall of the anvil-groove 21,

the same are forced outwardly or Iiared until` they assume a position within said groove 2l. When in this position, the eyelet 27 is locked to the extension 19 of the base 15 and the socketv member 14 as a whole is firmly attached to the cloth or other fabric.

When the two members of my device are attached to the cloth or fabric in the manner described, they may be interlocked one with the other by forcing the stud 2 through the contracted throat 30 and into the cavity 18 in the socket member 14. In passing through IOC IIO

the contracted throat of the socket member der formed by the bead 30 and preventsthe' two members of the device from being accidentally separated one from the other. the stud 2 has its resiliency given to it by its radially-slotted concentric and integral an- AsV nular walls and also by the spreading action of the engaging portion 23 of the socket member on the radiating spring members of the stud, when the stud and socket members are in locking engagement a greater spring action and a more secure locking action is obtained with the same weight of metal than can be obtained in similar fastenings otherwise constructed, and this without interfering with the easy and immediate vertical separation ofthe members when desired. Furthermore, by reason of the fact that the different sections of the stud 2, formed by the slots 6 therein, are integral with each other, with the anvil 5, and with the base-flange 3greater rigidity and lasting properties or qualities of the device are obtained.

In the form of my invention illustrated in Figs. 10 and 11 of the drawingsithe two parts of my fastening device are shown as oblong in shape with rounded ends. The stud member 1"L has the stud 2, formed with the slots 6, radiating from the center of its semicircular ends, forming the radiating spring portions 31 and the intermediate, elongated, imperforate, straight, and parallel spring portions 32 on opposite sides of the rentrant cavity 4. The socket member 14L is shaped toconform to the stud member 1 and is similar in all respects to the socket member 14, heretofore described, except that it is elongated instead of round. This construction of my device operates in the same manner as that illustrated in Figs. 1 to i) of the drawing, but by reason of the fact that the parts are elongated in shape horizontal or lateral turning movement of one with respect to the other is eifectually prevented. Furthermore, the locking force exerted by one of the parts on the other is increased by reason of the increase in the extent of frictional contact be-4 tween the two.

In the modified form of my invention illuse trated in Figs. 12, 13, and 14 of the drawings only two pieces of metal are vused in the construction of the respective members. The base-plate 33 of the socket member is formed with a downwardly-extending central cavity 34, the under side 35 of which constitutes'an engaging portion corresponding to the engaging portion 23 of the socket member in the preferred form of my invention. To this base-plate 33 is secured a socket-piece provided with a downwardly-projecting tubular extension 36, having an inwardly-crimped lower end 37, constituting the contracted throat for the socket and the shoulder against .which the cooperating stud engages. The

base-plate 33 is secured to the socket-piece by crimping or upsetting the edges thereof around the edges of the flange 33 of said socket-piece, as shown at 39. The flange 38 and base-plate 33 are provided with openings 40, by means of which the socket member may be stitched to the cloth or other fabric. Any other equivalent att-aching means, however, may be substituted for these openings.

The stud 41 of the stud member is substantially the same as the stud 1 in my preferred construction, the difference being that said stud is somewhat more elongated vertically, so as to properly tit within the extension 36 of the socket member, and the base of said stud member is provided with openings 42, by means of which said stud member may be sewed to the cloth or fabric. When the two parts of the device are in place, as shown in Fig. 14 of the drawings, the projection 35 on the base-plate 33 of the socket member lits within the cavity in the upper end of the stud 4l and prevents, independent of the locking means between these two parts, the lateral displacement of one with respect to the other, and otherwise acts in the same manner as the corresponding part in the preferred form of the invention.

In the construction of the socket member illustrated in Fig. l5 of the drawings the baseplate 43 is struck up at its center to form a cavity 44 and is then bent downwardly to form a cavity 34 and an engaging portion 35 within the cavity 44. AThe said base-plate 43 is secured to a socket-piece similar to that illustrated in Fig. 12 of the drawings.

In Fig. 16 of the drawings the socket-piece 36 is dispensed with altogether, and instead the base-plate 45 is struck up at its center to form the cavity 46, and then bent inwardly to form the cavity 34, with the engaging portion 35 on the opposite side thereof, substantially as shown in Fig. 15 of the drawings. In addition to what is shown in Fig. 15, however, there is provided an inwardly-extending bead 47 on the base-plate 45, which constitutes the contracted throat of the cavity 46 and serves as a shoulder against which the stud member bears when the two parts are in interlocking relation.

In all forms of my invention the stu-d 2 and the parts with which the same cooperates may be of circular, elliptical, or other suitable shape in plan or cross-section, When said stud and the socket in which it fits are elliptical or elongated, turning movement of the stud in its socket is elfectually prevented.
